Huge coronary perforation during percutaneous intervention sealed by injection of polyvinyl alcohol microspheres

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Device Technology

Background:

• Percutaneous coronary intervention (PCI) is a common procedure for treating coronary artery disease.
• Coronary perforation is a rare but life-threatening complication of PCI, potentially leading to cardiac tamponade or acute myocardial infarction.
• The incidence of coronary perforation has increased due to more complex PCI procedures, highlighting the need for effective management strategies.

Observation:

• A case of coronary perforation occurred during a complex percutaneous coronary intervention procedure.
• The patient developed a life-threatening complication requiring immediate intervention.
• Standard management protocols for coronary perforation were not yet established.

Findings:

• The study reports the first successful management of coronary perforation using intracoronary injection of hydrogel microspheres.
• Hydrogel microspheres were effectively delivered to seal the perforation site.
• The procedure resulted in successful closure of the coronary artery perforation.

Implications:

• Intracoronary hydrogel microspheres represent a novel and effective therapeutic option for managing coronary perforation during PCI.
• This approach may reduce the risks associated with traditional management strategies.
• Further research is warranted to validate the safety and efficacy of hydrogel microspheres in a larger patient cohort.
